Answer 1

Given :

⬤ Perimeter of Rectangle is 32 m.

⬤ Length of Rectangle is 7 m.

To Find :

⬤ Breadth of Rectangle .

Formula Used :

$\bf[\:{Perimeter \: of \: Rectangle = 2(l+b)}\:]$

l = length

b = breadth

Solution :

Let :

• Breadth of Rectangle be b .

According to the Formula :-

32 = 2(l + b)

32 = 2(7 + b)

32 = 14 + 2b

32 - 14 = 2b

18 = 2b

18/2 = b

9 = b

Therefore , The Breadth of the Rectangle is 9 m.

Check :

32 = 2(l + b)

32 = 2(7 + 9)

32 = 2(16)

32 = 32

Hence Checked.
